Constructing the USERADD_PARAM_${PN} value with += (as done before)
resulted in having a whitespace added for each entry not having its
PACKAGECONFIG parameter activated.

This is not only a cosmetical issue. The useradd class concatenates all
useradd commands from all subpackages of a package by doing a
";".join(). When having a useradd command that ends with ";" and some
extra spaces, concatenation will result in an empty useradd argument
("commandA;    ;commandB"). The useradd command will be called with this
and make the Yocto build break by returning an error code.

Fortunately, there is no problem when having a "commandA;;commandB" in
the useradd string, this will be ignored. Thus using "_append" instead of
"+=" is sufficient here.
